Besides the twigs, if you look closely at the media you will find peat mixed together with sphagnum peat.

I figure Neps will do fine unless they have already mix fertilier in the media. If it is still poor in nutrients, I think some drosera might do well too. But if you are using this media to grow your CPs in a terrarium or grow chamber indoors, fungus will grow in the media if it has normal peat in it. As you all know if it is purely sphagnum peat, fungus will not grow.
